To'l allw'hom 'it may concern:

Be it known that I, Encan H. Co'rrnnm., a

new and' useful Improvement in Cutting and Folding Machines, of which the followin lis a specification. V y

his invention relates to an improvement in 'cutting and 'folding machines and has particularly for its ob]ect to'provide lnovel means for associating and folding together sheets cut -from the printed web fed from the press with cover and insert sheets cut and fed froml previously printed webs, the

-niechanisins being so arranged that a plurality of sheets cut from the web fed fromv the press may be collected, a plurality of sheets cut and fed from` the previously printed insert supply ma'y be collected and the so collected groups of sheets be assembled with a sheet from the previously printed4 cover sup ly and the whole `folded together -andelivered to a predetermined point.

In the accompanying drawings, Figure 1 is-.al view '1li side elevation of a portion of acutting and foldin machineshowing the gearedconnections or driving the several parts at -their properspeeds with relation to. one another, Fig. 2 is a vertical-longitudinal section through the portion o f the 'maehineshown in Fig. 1, Fig. '3 is an en- 'larged .detail section taken inside .the side framing liowingmore clearly the cams` for actuat g the folding mechanism of the folding cylinders, Fig. 4 is a detail section on an enlarged scale adjacent tothe opposite side framing showing the arrangement of cams for controlling the operations' of the grippers on' the several cylinders, Fig. 4a is a detail plan of one of the cams for controlling the operation of the opening cam for the grippers on the sheet collecting cylinders, and Fig. '5 is a detail section showing vthe. cam forfcontrolling the movement of the floating folding bla e on the male folding cylinder.

The side frames of the machine are denoted by 1 and 2. Male and female folding c linders 3 and 4 are mounted between the side frames, the male cylinder being provided with a set of grippers 5 and a floatin folding bladel 6 and the female folding cy der be' provided with a set of grippers 7 and floating folding jaws 8 which are arranged to coact with the floatin foldin blade 6 of the male folding cylin er. Co lecting cylinders 9 and 10 are arranged ad- ]acent to the male folding cylinder 3, the collecting'cylinder 9 being rovided with a set of rippers 11 and the co lcting' cylinder wit` a set of grippers 12. A. transfer cylinder 13 is located adjacent to the female folding cylinder 4, which transfer cylinder' is provided with,a set of grippgrs 14. Thel web -15 is fed from the printing press, not shown herein, past feedin tapes 16 through rotary cutters 17, 18, an from thence between stationary guides 19, 20 into position to`-be engaged by the set of grippers 11 on theA collecting cylinder 9. printed insert web 21 leads fro'in a roll 22 past feeding ta es 23, through rotary cutters 24, 25 an from thence between stationary guides 26, 27 ,i into position to be en raged by the set of grippers 12 of the co lectin cylinder '10. The -previousl printed insert web 21 may be wound wit an offset web 28 for preventing the smutting of the insert web, the ofset web being wound olf the roll 22 on to the roll 29 as the insert web is unwound from the roll 22. The' previously past the feeding tapes 31 through the rotary cutters 32, 33, and between stationary guides 34, 35, into position to be en aged by the set of grippers 14 of the trans er c linder 13. The cover web is Wound wit the offset web 36 on the roll 37 to prevent smut-- ting of the cover web and the ,offset web 36 is unwound from the roll 37 on to the roll 38 as the cover web 30 is iinwound from the said roll 37.

l The several mechanisms are driven from the press through the train of gears 39, 40, 41 tothe s aft 43 of the male folding cylinder 3. The female folding cylinder 4 is driven at the same speed as the cylinder 3 by means of a gear 44 on the shaft 43 of the cylinder 3, which meshes with a gear45 on the shaft 46 of the female foldin cylinder 4. The collecting cylinder 9 is tions to one of the malefolding cylinder 3, by a gear 47 fixed to the shaft 48 of the cylinder 9, which gear 47 meshes with the ear 42 of the cylin er 3. The feed roller s aft 49 for the cylinder 9 is driven from the said cylinder by means of a gear 59 which meshes printed cover web 30 leads' the ear 41 meshing with'a gear 42 fixed' A previously aoy with the gear 47. The previously printed insgrt sheet supply collecting cylinder 10 is driven tivo revolutions to one of the male folding cylinder by providing the shatt 51 ot' the cylindcrl() with a gear 5;), which meshes with the gear 44 ot' the cylinder 3. The feed roller shaft 53 t'or the cylinder 10 is provided-with a gear 54 which meshes with the gear 52 onthe shaft 51 vof the cylk inder 10. Sheet pressure rollers 50, 57, 58 engage the periplieries ot' the cylinders 4, 9, 3 and 10 respectively. The -previonsly )rinted cover sheet transfer cylinder 13 is Criven a revolution for every revolution of the female folding cylinder Y4 but at varying speeds by irregular gears 59, 00, the gear 59 being iiXed to the shaft 46 of the cylinder 4 and the gear 60 being lixed to the shaft 01 of the cylinder 13. The feed roller shaft 62 for the cylinder 13 is provided with a gear `63 which meshes with la gear 64 fixed to the shaft 61 of the. said. cylinder 13.

. Carry ng tapes 65, (58 are arranged to convey the assembled and folded group of press, insert and cover sheets fromthe folding cylinder 4, through slitters 651i, (36* to a predetermined point, such for instance as a collecting pocket carrier 67 like that shown iny my AUnited States Letters Patent No. 749,362 dated January 12, 1904.

The insert offset roll 29 is driven from the gear of the cylinder 4 through a train of gears (i8, 09, 691", 70, 71, 72, 72*,

shaft 73 and train or" gears 73i, 74, 75, 7'5,4

77. The cover odset roll 38 is driven from the gear 08 through a train of gears 09, 69%, 80, 81, 82, 83, 84. The rotary cutters 17, 18, are driven from the gear 45 through a train of gears 8b, 87, 88, 89, 90 and the rotary cutters 24, 25, are driven from the gear 88 through a train of gears 91, 92, 93, 94. The rotary cutters 32, are driven from the gear 87 through a train of gears 95, 96, 97 i The feedingI tapes 23, 16 and 31 are driven from their respective cutters by suitable gearing Which need not he specifically described.

The set of grippers 11'on the sheetcol- '.lecting cylinder 9 is opened every revolution to receive the advance edge of a sheet by means of .a liXed cam 98 which engages the gripper lever 99 at the proper time. The set of grippers 11 isv opened every seeond revolution to transfer a collected group. of two sheets to the set of grippers 5 on the male folding cylinder 3, by means of a movable opening cam 100, which cam is throvvn into and out of position to engage the lever 99 by means of a rock lever 101 operated by a cam 102 driven from the shaft 51 of the collecting cylinder 10 through gears 103, 104, 105,. The set of grippers 12 on the col- --lecting cylinder 10 is opened-every revoluti'on to receive the advance edge of sheet from the cutters 24, 25, by a stationary cam 106 which is arranged in position to engage the gripper 'opening lever l 107 at the required time. Ths setof grippers 12 is opened every sec nd revolution of the collecting cylinder for transferring the col-v lected group of two slieets to the set of grip pers 5 on thefolding cylinder 3, by means of a movable opening cam 108, which camv is moved into and out of the path of the lever 107 by a lever 109 which is operated by a cam 110, which cam is driven from the gear 103 on the shaft 51 through a gear 111; The

`set o1 grippers 14 on the transfer cylinder 13 is opened to receive the advanceedge ot' the cover sheet as 1t leaves the guides 34, 35,

.by means of a fixed cam 112 which is arranged in position to engage the gripper opening lever 113 atthe proper time. Another tixed cam 114 is arranged in position to engage the lever 113 at the proper time to transfer the advance edge of the cover sheet from the set of grippers 14 to the set of grippers 7 'on' the female. folding cylinder 4. A fixed cam 115 is arranged in position toy engage the opening lever 116 of the vset of grippers 7 at the proper time to receive the advance edge of the cover sheet troni'the set of grippers 14. A second fixed cam 117 is arranged in position to engage the lever 11GI of the set of grippers 7 at the proper time to transfer the advance edge of the 'cover sheet tothe setof grippers 5 on the male foidingA cylinder 3. A Xed cam 118 is arranged in position to engage the opening lever 119 of the set of grippers 5 on-the male folding cylinder 3 at the proper time to receive the collected group otwo insert sheets from the collecting cylinder 10. A second. iixed cam 120 is arranged in position to engage the lever 1-19 at the proper time to open the set of grippers 5 to receive the collected group of tvvo sheets from the ,main press.- A third fixed cam 121 is arranged in position to engage the lever- 11.9 to openl the `set of grippers 5 to receive the advancev edge of the cover sheet from the setof grippers 7. A fourth xed cam 122 is arranged in position to engage the lever 119 tofopen the set of gripp'ers v5 to release' the advance edges of the sheets at the' proper time of folding the same from the male folding cylinder on to the female folding'cylinder.

The coaction of the folding devices on the cylinders 3 and 4 is obtained asfollows. A fixed box cam 123 is arranged to control the Hoatingmovement of the'blade 6 through the truck roller y124 and a. cam 125 is arranged to cont-rol the tucking movementy of the said blade by its engagement with Athe stud roller 12,6. A lixed cam 127 is arranged to control the ioating of the folding jaws by its engagement lwith the truck roller 128 and a iixed cam 1 29 is arranged to control the opening of said jaws by'its engag'ement with the stud roller 130. The opening revolutions to one revolution of the folding cylinders so that two sheets at a time are vthe collecting cylinder 10.

transferred to the grippers 5 on the folding cylinder 3. The rotary cutters 94, and the collecting| cylinder 1() also complete two revolutions to one revolution of the folding cylinders so that two insert sheets are transferred at a time to the grippers 5 Von the folding cylinder The rotary cutters 32, and the transfer cylinder 13 rotate one revolution for one revolution of the folding cylinders .sothat one cover sheet at a time is transferred to the grippers 7 on the folding cylinder 4. The irregular gears 59. 60 are so shaped that the cylinder 13 will be caused to travel at the speed of the cover web at the time the grippers 14 engage the advance edge of the. cover sheet and at the surface speed 'of the folding cylinder 4 at the time thatrthe advance edge of the cover sheet is transferred to the grippers 7.

In operation, the cutters 24, 25, cut successively sheets from the insert web and feed -them down between the guides 26, 27 into position to have the advance edge of an insert sheet engaged by the grippers-12 on After two insert sheets have been collected on the cylinder 10, they are transferred to the grippers 5 2 on the folding cylinder 3 when the said 'gi'ippers are brought together with the grippers '12. In the meantime the cutters 32, cilit successive sheets from the cover web and feed the sheets one at a time down between the guides 34, 35, into position to have the agrippers 7 ofthe fo ding cylinder and the 50` 4ifipliers 14 ofthe transfer cylinder are r'ou'ght together. The rotary cutters 17, cut sheetsfrom the web fed from the niinpress and feed them down between the guides 19, 20 into position to be collected upon the cylinder `9. After the grippers 11 have engaged the advance edges of two sheets, the two sheets are transferred to I the folding cylinder 3 as the grippers 5 and 'grippers 11 are brought together. The fun ther rotary movement of the folding cylinders 3 and 4 bring the grippers 5 and'grippers 7 together and thus permit the advance 'l edge of the cover sheet on the folding cylinder 4 to be transferred to the folding cylinder 3. As the folding mechanism of the cylinders and have `its advance edge rein the carrier 67. Means for imparting the successive movements of the pocket carriers to collect a series of folded signatures therein forms no part of the present invention and will therefore not be specifically described, it heilig understood that the folded signature from the tapes may be `slit into therequired number of smaller signatures and then deposited at proper intervals into the pocket carrier to produce the result desired.

It can be readily understood that instead of transferring the advance edge of the cover sheet from the folding cylinder-4 to the folding cylinder 3 to be combined with the insert and main web sheets thereon, the opening of the grippers may beso timed that the cover sheet will not be transferred to the cylinder 3 but will be fed between the leased from the grippers 7 in ample time to permit the assembled insert, main web and cover sheets to be folded together and fed between the tapes 65, 66.

.It will be seen t-hatthe machine as hereinabovc set forth accomplishes `the assembling and. folding together of sheets from the main press and from the insert and cover supplies without the necessity of cmploying formers, turning-bars or carryingl tapes.
